There is generally no way to self-test for early stage of liver cancer. Determination of early stage of liver cancer generally needs to be combined with clinical symptoms and examination results. The staging of liver cancer generally needs to be judged according to the size of the tumor tissue, whether there is infiltration of surrounding tissues and the presence of distant metastasis, etc. There is no way to determine the above situations by self-testing, so there is generally no way to self-test for liver cancer. Early stage of liver cancer usually has no obvious clinical symptoms, and only when it develops to a certain degree, it will lead to symptoms such as loss of appetite, emaciation, pain, jaundice, diarrhea, abdominal distension and so on. If patients suffer from hepatitis, long-term alcohol consumption or family history of liver cancer, they need to have regular ultrasound and liver function tests every year in order to detect early liver cancer. It is recommended to adopt a healthy lifestyle, reduce smoking and drinking, and avoid eating moldy food.
